JOHNSON CITY, TENNESSEE, ASSIGNOR TO AMERICAN 'GLANZSTOFF GORIORATION, OF NEW YORK, N.

Y., A CORPORATION OF DELAWARE SPOOL .HOLDER Application filed September 4, 1931.

My present invention relates to the provision of a novel spool holder.

It is an object of my present invention to provide a new spool holder having means to hold a spool in place thereon.

A further object of my invention is to provide simple and efficient means to hold a spool securely on. a spool holder by providing 10 whereby the said spool may readily be locked in place.

A still further object of my invention is to provide a spool holder with an upstanding portion having formed therein radially disposed slots in which are fitted securing means held in place b means of a flexible or resilient hosing or tube These and other objects of my invention will become more apparent from a perusal of go the following description and a study of the annexed drawing in which: 7

Figure 1 is a sectional view taken along lines 1--1 of Figure 2;

Figure 2 is a sectional view taken along lines 2-2 of Figure 1 the spool being omitted.

Figure 3 is a perspective view of one of my holding means.

Referring now more particularly to the drawing, I have shown a spindle 1 having secured thereto by any suitable means my new holder designated by 2. My new holder comprises a cylindrical base 3 having formed therein a bore 4 adapted to receive the spindle.

- The upper portion 5 of the base provides a 35 suitable seat 5 for the beaded end of a spool 7.

Located inwardly on the periphery of the base is an upstanding cylindrical member 8, which, as may clearly be seen from Figure 1, is an integral part of the holder. This member is providedwith a bore 9 communieating with the bore 1, but of larger diameter, thus providing a seat 10 for the hose or tube 11. This hose, or tube, may be made of any suitable material, as, for example, soft rub- .ber, and fits snugly against the inner wall of the cylindrical member 8.

This member is provided at spaced intervals with integral ribs 12 extending the length thereof and extendingl outwardly fits the in- 18 along one of the long sides thereof. The

side of the spool 7. Elongated slots 13 are formed in these ribs and communicate with the bore 9. The top and bottom walls of each slot are inclined inwardly as is clearly shown at 14, Figure 1. Fitting within these slots are correspondingly shaped holding members or blades 15. When the spool is placed'on the holder the holding members or the spool holder with radially disposed means lades are forced inwardly and because of the inclination of these slots, these blades are forced not only inwardly but also outwardly from the base 3, thus forcing the top of the blade against the upper inclined surface of the slot. Due to the resiliency of the holding members the pressure thus exerted upon the upper wall of each slot will tend to force the blades downwardly, thus holding the spool firmly against the base 3.

Referring now to Figure 3, I have shown one of the blades or holding means in perspective. As ma be readily seen, each blade or holding meln er comprises an elongated body member 16 having a tapered portion 17 formed on the upper end and an abutment I5 tapered portion functions as a cam surface for a purpose to be hereinafter described, and the function of the abutment means 18 is to prevent the holding members or blades from dropping out of the slots provided therefor. The abutment 18 as may clearly be seen, is widerthan the slot.

In the assembly of my holder with the spindle, the holder is secured to the spindle by any suitable means such as by a nut. The tube or hose tends constantly to force the holding members or blades outwardly, the outward movement thereof being limited by the abutments. The spool 7 is then positioned on the holder and its beaded edge, striking thetapered portion of the blades, forces the said blades inwardly against the tube. B virtue of the inclined walls of the slots an .the correspondingly shaped portions of the limiting the outward movement thereof and g with said resilient tube, whereby 001 is placed on the holder the blades in contact therewith.
